Other Parts Discussed in Thread: TUSB214
Dear TI experts,
My customer tests TUSB214-Q1 in their own PCB. and they have a question about timing diagram.
they looked SLLA593 document, figure 3-3 and figure 3-4.
it explains about CD pin goes high and after ENA_HS goes high.
1. when the USB communication is disconnected, CD and ENA_HS will go to low.
is there any possibility that ENA_HS pin remains high? what is the condition about ENA_HS pin high?
2. is there any possibility that ENA_HS pin goes high, and after CD pin goes high? (generally CD pin goes high first.)
Please check this issue. Thanks.
Best regards,
Chase
